After a delay, a menu offers a selection of boot devices (see the
following example).

Select a boot device from the list.

To boot from a physical CD/DVD or from an ISO image, select CD/DVD.

Control passes to the OS installation program on the media.

Do one of the following at the boot prompt, depending on which type
of interface you want to use:

For text mode, type the following command: boot:linux text.

For graphical mode, press Enter at the boot prompt.

Refer to the Red Hat Enterprise Linux Installation Guide to guide you through the remainder of the installation process.

Note - If you already have an operating system besides Linux installed (for example, the
Solaris OS), it will appear as a partition during the installation process. If
you choose to install RHEL on that partition, it will overwrite the OS.
If you wish to preserve the partition, you must install RHEL on a
different partition.
